Notification LED Driver Development Concepts (Windows CE 5.0)
A notification LED driver handles turning on and off notification LEDs on the hardware platform. You can use the notification subsystem APIs to implement PUN_LED notifications by customizing %_WINCEROOT%\Public\Common\Oak\Notify\Notifext.cxx for your hardware platform. For more information on the notification subsystem, see Implementing Notifications.
